The hostname of the VMs spawned through openstack are always in lower cases regardless of the name given through nova.

Issue

• The hostname of the VMs spawned through openstack are always in lower cases regardless of the name given through nova.

• How to set instance hostname with combination of uppercase and lowercase?

• When creating instance in uppercase, instance host name is set in lowercase in instance OS side.

• In the following example, we see the name of the VM is AbCd:

(overcloud) [stack@undercloud-0 ~]$ openstack server list
+--------------------------------------+---------+--------+--------------+-------+---------+
| ID                                   | Name    | Status | Networks     | Image | Flavor  |
+--------------------------------------+---------+--------+--------------+-------+---------+
| e6ad7ccc-df50-4b5a-8b8d-b0e1df9a30c8 | 'AbCd'  | ACTIVE | n1=10.1.1.6  |       | m1.nano |
| 5a7cdf7d-6500-401f-85e5-8e29a437eefc | AbCd    | ACTIVE | n1=10.1.1.16 |       | m1.nano |
+--------------------------------------+---------+--------+--------------+-------+---------+

• When logging on the VM, the hostname is all lowercase:

abcd login: root
Password: 
[root@abcd ~]# 

• Is it possible setting instance hostname in combination of uppercase and lowercase automatically?
